Product Description
This product is a TTL to RS485 module that converts TTL signals to RS485 signals for single-chip serial ports, UARTs, and lightning protection hardware. It supports automatic flow direction control and automatic switching of transmission and reception modes. It has a wide voltage range (3.0V ~ 30V) that allows compatibility between 3.3V and 5.0V systems and signals. It comes with wiring terminals and silicone wires for easy connection. It uses high-quality imported chips that offer powerful performance, lightning protection design, strong anti-interference ability, and industrial grade. It has a one-year warranty! Using this module is as simple as operating a serial port.
Features
- This module fully considers the 485 bus lightning protection design and anti-interference design.
- It has extremely high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance.
- When long-distance transmission in the field, the module is connected to the earth Access to the earth can play a good role in anti-interference and lightning protection, making the 485 bus more secure; the indoor short-distance transmission can not be connected to the earth.
- With standard 2.54 pitch pin headers for your secondary development
- With 120 ohm matching resistance, short-circuit R0 to enable matching resistance, short-circuit is recommended for long-distance transmission.
- Support multi-machine communication, at least 40 nodes can be connected to the same network
- It can be hot-swapped and there will be no signal thrombosis
- Anti-interference wiring and copper laying method to prevent signal interference
